INTERC-IANGEABLE EESILIENT HEEL.

T 0 all whom if may concern Be it known that I, HENRY P. ROBERTS, ot

Boston, in the county of Sudolls and State of Massachusetts, have invented certain new and useful Improvements in Interchangeable Resilient Heels, of which the following is a specification.

This invention relatos to interchangeable resilient heels.

The object of the invention. is to provide a resilient or rubber heel which may be readily detached from the heel of a shoe and replaced on another, whereby a pair of heels are interchangeable so that they may be worn evenly, thereby lengthening their life and increasing their comfort to the wearer.

I will describe my invention in the following speciiication and will point out the novel features thereof in the appended claim.

In the accompanying drawing Figure l is a sectional side elevation showing a rubber heel attached to the heel of a shoe with one embodiment of my invention, Fig. 2 is a fragmentary planl view of the same, Fig. 3 is a perspective view o1' the stationary member of the attaching device, Fig. i is a perspective view of the removable member of the attaching device, Fig. 5 is a fragmentary plan View of a heel secured in place by a modified form of the invention, and Fig. 6 is a perspective view of the sta` tionary member of this modified form.

As illustrated in Figs. 1 to 4, inclusive, a removable heel 10, preferably of rubber, is secured to the leather heel 12. This is accomplished by a pair of interengaging members 14 and 16, which are detachably connected. rl`he member 14 comprises a sheet metal plate having a series of nail holes 18, and provided with a plurality of upwardly extending 'ears or projections 20, each provided with apertures 22, preferably rectangular. The member 14: is preferably sunk into the outer lift of the heel of the shoe so that the lower face of the plate 14 is flush with the lower face of said lift. This member is preferably secured in place by nails passing through the holes 18 therein.

The heel 10 is provided with recesses which are adapted to receive the ears 20, and also with a series of passages extending longitudinally in, alinement with the aper- Speciflcation of Letters Patent.

tures 22 andfccmmunicating with said recesses. These passages are adapted to receive prongs 2%,25 and 2li ot' the removable securing member 1G. These prongs are connected to a bar or plate 2S extending -at right angles to the plane of the prongs and is adapted to lie against the breast ot the heel 12 when the resilient heel 10 is secured in place on the shoe. It desired, the plate 28 may be secured in place to prevent the securing member from working out un- \der the action of the wearer while walking,

it being understood that the prongs 24, 25 and 26 frictionally engage the walls of the passages in the rubber heel.

As illustrated in Figs. 5 and 6 a stationary memberv 30 is provided, having offset ears 32 and an overturned ear 34. rlhis member is aiiixed to the heel as described above, and the ears 32, 34 are received in correspondingly located recesses in the rubber heel 40, and this heel is provided with longitudinally extending passages which are adapted to receive the prongs of the member 16.

It will be noted that the ears or projections on the stationary or tiXed members are symmetrically' located so that they will enter either heel ot' a. pair; and it is merely necessary to insert the prongs 24, 25 and 26 into the heel to engage said ears to hold the rubber heel in place. The prongs are arranged to lit the passages in the heel tightly to prevent accidental removal of the prongsv therefrom.

By reference to the drawing it will be observed that one of the projections 2O and the projection 34 are located on the longitudinal median line of their plate, and in addition there are two pairs of project-ions, one pair on each edge of the plate, one projection being oneach corner thereof. The securing member comprises three prongs, the central prong being arranged for engagement withthe single central projection, and the side prongs being each arranged for engagement with the corresponding pair of projections on the-plate which is aliixed to the outer lift or the heel. a'
